public struct VertexBillboard { public Vector3 Position; public Vector2 TexCoord; public Vector4 AdditionalInfo; public VertexBillboard(Vector3 Position, Vector2 TexCoord, Vector4 AdditionalInfo) { this.Position = Position; this.TexCoord = TexCoord; this.AdditionalInfo = AdditionalInfo; } public static readonly VertexElement[] VertexElements = new VertexElement[] { new VertexElement(0, 0, VertexElementFormat.Vector3, VertexElementMethod.Default, VertexElementUsage.Position, 0), new VertexElement(0, 12, VertexElementFormat.Vector2, VertexElementMethod.Default, VertexElementUsage.TextureCoordinate, 0), new VertexElement(0, 20, VertexElementFormat.Vector4, VertexElementMethod.Default, VertexElementUsage.TextureCoordinate, 1), }; public static readonly int SizeInBytes = sizeof(float) * (3 + 2 + 4); } You see this format accepts an additional Vector4, called AdditionalInfo, next to the usual Position and TexCoord information. You identify this extra Vector4 as another TextureCoordinate. To distinguish both TextureCoordinates, notice that they differ in the last argument, which is the index. This means the real texture coordinate can be accepted in the vertex shader as TEXCOORD0 and the additional Vector4 as TEXCOORD1 (see recipe 5-14). Next, you replace every occurrence of VertexPositionTexture with your newly defined VertexBillboarding (you ll want to use Ctrl+H in XNA Game Studio to do this). Finally, you can adjust your CreateBBVertices method and pass up to four additional float values with every vertex: private void CreateBBVertices() { billboardVertices = new VertexBillboard[billboardList.Count * 6]; int i = 0; foreach (Vector4 currentV4 in billboardList) { Vector3 center = new Vector3(currentV4.X, currentV4.Y, currentV4.Z);

The following code expands the preceding class D by adding two methods: One method sets the values of the two data members. The other method displays the values of the two data members. class D { int Mem1; static int Mem2; public void SetVars(int v1, int v2) // Set the values { Mem1 = v1; Mem2 = v2; } Access as if it were an instance field public void Display( string str ) { Console.WriteLine("{0}: Mem1= {1}, Mem2= {2}", str, Mem1, Mem2); } } Access as if it were an instance field class Program { static void Main() { D d1 = new D(), d2 = new D(); // Create two instances. d1.SetVars(2, 4); d1.Display("d1"); d2.SetVars(15, 17); d2.Display("d2"); d1.Display("d1"); } } // Set d1's values. // Set d2's values. // Display d1 again and notice that the // value of static member Mem2 has changed!

Throughout the previous chapters, we have emphasized a basic concept: Plone is not simply a CMS it is a complex framework, a dynamic development environment that allows you to extend and customize features. In this section, in particular, we will cover the possibility of handling and publishing images and documents. You can easily perform these tasks with many CMSs, but with Plone you can also solve various complex use cases involving your document and image data. For example, you can add watermarks to images and allow for dynamic document generation from your web content. We will briefly discuss these use cases and figure out a good way to meet our needs. But remember, there is always more than one solution that can meet a demand.
